Season the chicken thighs with salt and black pepper.
Coat the chicken evenly with flour, shaking off any excess.
In a large skillet, melt 60 g of salted butter over medium-high heat.
Add the chicken thighs and sear for 4–5 minutes on each side until golden brown and cooked through. Remove from the pan and set aside.
Add the finely chopped shallot and minced garlic to the same skillet and sauté for 1–2 minutes until fragrant.
Pour in the dry white wine and simmer for 2–3 minutes, scraping up any browned bits from the pan.
Stir in the remaining salt, chili flakes, cayenne pepper, and dried oregano.
Reduce the heat to low and gradually whisk in the remaining cubed butter until the sauce is smooth and slightly thickened.
Add the chopped parsley and stir to combine.
Return the chicken to the skillet and turn to coat in the sauce. Simmer for 2–3 minutes to heat through.
Serve hot, garnished with extra parsley if desired.
Notes
Brown the Chicken First: I always make sure the chicken gets a nice golden sear; it adds so much flavor before the sauce even goes in.Let the Wine Simmer: I like to give the wine a couple of minutes to bubble away; it picks up all the flavor from the pan and makes the sauce taste richer.Add the Butter Slowly: I whisk in the butter a few cubes at a time so the sauce turns silky smooth without breaking.
